The outer surface of the convex thread 210 is threadedly connected with the inner wall of the gland body 22. An auxiliary tightening component is arranged inside the threaded annular sleeve 21. One end of the gland body 22 is provided with a tensioning and locking component. The tensioning and locking component comprises a shrinking thread sleeve plate 23 and a locking nut 24. The end of the gland body 22 away from the gland body 22 is provided with a terminal waterproof component. The terminal waterproof component comprises an external waterproof boss 25. In this embodiment, a ring terminal 14 is used to connect the end of the multi-core wire 13, replacing the traditional quick-plug terminal for plugging into the compressor, thereby avoiding the influence of jitter on the terminal plugging effect, and by adding a gland mechanism 2 on the connecting harness 1, the cable and the docking device are tightly connected together to prevent the cable from loosening or falling off due to external force during use, thereby playing a sealing and tightening role in the docking with the air-conditioning compressor equipment, and the IP position is multiple-protected by cooperating with the tension locking assembly and the end waterproof assembly. With the setting of the auxiliary tightening assembly, the cable can be prevented from radial torsion and axial displacement at will, thereby protecting the cable skin from damage and extending the overall service life; further solving the problems of single connection method between the existing cable and the gland, inconvenient installation and disassembly, and poor protection effect.

[0022] Embodiment 2: On the basis of embodiment 1, in order to realize the tightening of the threaded annular sleeve 21 and the gland body 22, this embodiment further proposes that a threaded docking platform 211 is fixedly installed at one end of the threaded annular sleeve 21, and the outer surface of the threaded docking platform 211 is threadedly connected to the inner surface of the compressor female joint 3, and an end of the threaded annular sleeve 21 away from the threaded docking platform 211 is provided with an end rubber waterproof ring 222; the end rubber waterproof ring 222 is a circular boss ring structure, and the outer end of the end rubber waterproof ring 222 is fixedly connected with a waterproof membrane 2221, and the end rubber waterproof ring 222 is fixedly installed on the inner ring surface of the gland body 22; the outer surface of the gland body 22 is provided with an auxiliary force-bearing component, and the auxiliary force-bearing component includes a force-bearing nut 221, the inner ring surface of the force-bearing nut 221 is fixedly connected to the outer surface of the gland body 22, and the outer surface of the force-bearing nut 221 is provided with an embedding groove 2210, and the inner surface of the embedding groove 2210 is movably embedded with a soft rubber convex strip 2211; In this embodiment, the threaded annular sleeve 21 is first sleeved from one end of the connecting harness 1, and one end of the threaded annular sleeve 21 is adapted to be connected with the plug-in connector compressor female connector 3 on the air-conditioning compressor.

When the two are close, the outer side of the force nut 221 is held by hand to screw the gland body 22. Under the action of the thread adaptation, the thread groove in the gland body 22 is connected to the convex thread 210 part on the surface of the threaded annular sleeve 21 Thread adaptation, when the gland body 22 is screwed into place, the end rubber waterproof ring 222 on the inner side of one end of the gland body 22 close to the external waterproof boss 25 contacts the end of the threaded annular sleeve 21 away from the compressor female connector 3. The reason why the end rubber waterproof ring 222 and the waterproof membrane 2221 are added to the end of the gland body 22 is to play a role in waterproofing and dustproofing the inner side of the threaded annular sleeve 21. It is worth noting that the end rubber waterproof ring 222 here is made of soft and elastic nitrile material throughout, which plays a role in waterproofing and dustproofing, and can also enhance the protection of cable clamping and reduce the damage to the outer skin; It should also be noted that the outside of the cable gland body 22 is connected with a force-bearing nut 221, and the mounting groove 2210 accommodates the soft rubber ridge 2211. When the operator rotates the cable gland body 22, the hand is stressed by contacting the soft rubber ridge 2211, ensuring that the screwing is more labor-saving and no external tools are required.

[0023] Embodiment 3, on the basis of embodiment 2, in order to realize the limiting of the connection harness 1, this embodiment further proposes that the auxiliary tightening assembly includes an inner ring 26, the inner ring 26 is fixedly mounted on the inner ring surface of the threaded annular sleeve 21, and the outer surface of the inner ring 26 is fixedly mounted with reinforcing ribs 261, and the reinforcing ribs 261 are arranged in a circular array about the center axis of the inner ring 26, and one end of the inner ring 26 is fixedly connected with a clamping head 262, and the clamping head 262 has a feather-like structure, and the outer surface of the clamping head 262 is movably connected to the inner ring surface of the end rubber waterproof ring 222; In this embodiment, after the gland body 22 and the threaded annular sleeve 21 are butt-jointed and locked, the inner sleeve 26 connected to the inner side is sleeved on the outside of the connecting harness 1, and the clamping head 262 here is set as a feather-shaped annular structure, referring to Figure 10-11 It can be seen that when the cable gland body 22 drives the end rubber waterproof ring 222 to move toward one end of the compressor female connector 3, the inner ring of the end rubber waterproof ring 222 contacts the clamping head 262, so that the threaded annular sleeve 21 and the cable gland body 22 are docked and installed, while ensuring that the clamping head 262 is pressed tightly against the outer skin of the inner connecting wire harness 1, further ensuring that the connecting wire harness 1 will not be arbitrarily radially twisted and axially displaced, thereby protecting the cable skin from damage.

[0024] Embodiment 4: On the basis of embodiment 3, in order to achieve the waterproof effect on the end of the gland body 22, this embodiment further proposes an end waterproof assembly, the external waterproof boss 25 is fixedly installed at one end of the gland body 22 away from the compressor female joint 3, the inner ring surface of the external waterproof boss 25 is provided with a receiving groove 251, the inner surface of the receiving groove 251 is embedded with a sealing rubber ring 252, and the central inner surface of the sealing rubber ring 252 is provided with an extrusion groove; In this embodiment, refer to Figure 4-Figure 5 As shown, when the gland body 22 is adapted and connected with the threaded annular sleeve 21, the external waterproof boss 25 at one end of the gland body 22 is designed with an inwardly inclined opening, which can ensure that the sealing rubber ring 252 gradually contacts the surface of the connecting harness 1. The sealing rubber ring 252 first contacts the waterproof membrane 2221. The sealing rubber ring 252 here plays a role in preventing the cable from slipping and loosening. At the same time, the special structural design of the external waterproof boss 25 can avoid friction and bending at the contact position of the connector, thereby further enhancing the protection effect of the connecting harness 1. It should be noted that the receiving groove 251 here accommodates the sealing rubber ring 252, and the extrusion groove on the inner side of the sealing rubber ring 252 can provide space for the deformation of the sealing rubber ring 252.

[0025] Embodiment 5, on the basis of embodiment 4, in order to realize the bidirectional clamping between the threaded annular sleeve 21 and the gland body 22, this embodiment further proposes a tension locking assembly, one end of the shrinking thread sleeve 23 is fixedly connected to the end of the gland body 22 away from the external waterproof boss 25, and reserved grooves 230 are evenly provided on the inner wall of the shrinking thread sleeve 23, and the reserved grooves 230 are distributed in a circular array about the central inner surface of the shrinking thread sleeve 23, and a protective gasket 231 is attached to the inner ring surface of the shrinking thread sleeve 23; the inner surface of the locking nut 24 is threadedly connected to the outer surface of the shrinking thread sleeve 23, and the outer surface of the locking nut 24 is provided with a thumb groove 240, and a silicone gasket 2401 is arranged on the inner side of the thumb groove 240; a sealing gasket 241 is movably connected to one side of the locking nut 24, and the outer surface of the sealing gasket 241 is movably abutted with a sealing gasket 1 220, and the sealing gasket 1 220 is sleeved and installed on the outer surface of the gland body 22; In this embodiment, the threads of the threaded annular sleeve 21 and the gland body 22 are adapted and clamped, and the shrinking threaded sleeve plate 23 added to the end of the gland body 22 away from the external waterproof boss 25 is sleeved to the outside of the threaded annular sleeve 21. At this time, the thread on the surface of the shrinking threaded sleeve plate 23 is adapted to the thread on the inner wall of the locking nut 24 by screwing the locking nut 24. It is worth noting that reserved grooves 230 are evenly opened on the inner wall of the shrinking threaded sleeve plate 23, so that the inner diameter of the shrinking threaded sleeve plate 23 can be gradually reduced when the locking nut 24 and the shrinking threaded sleeve plate 23 are screwed together, so as to cooperate with the waterproof The provision of the protective gasket 231 enhances the flexible protection of the surface of the threaded annular sleeve 21 to avoid damage; and through the provision of the sealing gasket 241 and the sealing gasket 1 220, the sealing performance of the locking nut 24 on the gland body 22 is enhanced. It should be noted that thumb grooves 240 are evenly opened on the surface of the locking nut 24 to facilitate the operator's thumb to apply force, and a silicone gasket 2401 is installed on the inner side of the thumb groove 240 to protect the thumb, so that the locking nut 24 can be tightened more labor-saving and ensure that the wiring harness and the air-conditioning compressor interface are more precisely connected.

One end of the threaded annular sleeve 21 is connected to the end rubber waterproof ring 222 and the waterproof membrane 2221 to protect the skin of the connecting wiring harness 1, and then the gland body 22 is connected to the connecting wiring harness 1 as a whole. When one end of the gland is inserted and the two are close, the outer side of the force-bearing nut 221 is held by hand to screw the gland body 22. Under the action of thread adaptation, the thread groove arranged in the gland body 22 is thread-adapted with the convex thread 210 part of the surface of the threaded annular sleeve 21. When the gland body 22 is screwed into place, the end rubber waterproof ring 222 on the inner side of one end of the gland body 22 close to the external waterproof boss 25 contacts the end of the threaded annular sleeve 21 away from the compressor female joint 3. Step 2: After the gland body 22 and the threaded annular sleeve 21 are butt-jointed and locked, the inner side connected to the inner side is The collar 26 is sleeved on the outside of the connecting harness 1. When the gland body 22 drives the end rubber waterproof ring 222 to move forward to one end of the compressor female connector 3, the inner ring of the end rubber waterproof ring 222 contacts the clamping head 262, so that the threaded annular sleeve 21 and the gland body 22 are docked and installed, and the clamping head 262 is ensured to be tight against the outer skin of the inner connecting harness 1; step three, when the gland body 22 is adapted and connected with the threaded annular sleeve 21, the external waterproof boss 25 at one end of the gland body 22 is designed to be inclined inwardly, which can ensure that the sealing rubber ring 252 is gradually The surface of the connecting harness 1 is resisted, and the sealing rubber ring 252 first resists the waterproof membrane 2221.
